Our vision is to enable smallscale gold miners to achieve the same gold recovery rates as largescale miners but with a lower cost, scalable, mobile processing plant. Smallscale miners can find it difficult to operate profitably. In Australia alone, 85% of gold tenements are inactive. This trend can be reversed and they can now better afford to compete with the largescale .

· Mercurybased artisanal and smallscale gold mining (ASGM) causes more mercury pollution than any other human activity. 1 In this practice, mercury metal is used to extract gold from ore as a stable amalgam. The amalgam is then heated to evaporate the mercury and isolate the gold. While mercury amalgamation has been used for thousands of years to mine gold and silver, 2 it is .
Artisanal and SmallScale Mining (ASM): ASM is a collective term embracing both small scale and artisanal mining. It covers formal or informal mining which is characterised by low capital intensity and high labour intensity and relatively simple methods for exploration, extraction and processing. ASM can involve men and women working on an individual basis as well as those working in family ...
· In smallscale gold mining communities where inorganic, elemental Hg exposures are high, little is known about the effects of Hg on blood pressure. In 2011, we assessed the relationship between Hg exposure and blood pressure (BP) in a crosssectional study of adults from a smallscale gold mining community, Kejetia, and subsistence farming community, Gorogo, in Ghana's Upper .

· We estimate that artisanal and small scale gold mining releases between 640 to 1350 Mg of mercury per annum into the environment, averaging 1000 Mg yr 1, from at least 70 countries. 350 Mg yr 1 of this are directly emitted to the atmosphere while the remainder (650 Mg yr 1) are released into the hydrosphere (rivers, lakes, soils, tailings).
Smallscale gold mining activities have been carried out in the Guianas for over one hundred years. They continue to provide a source of livelihood for communities where alternative economic opportunities are limited. During the past fifteen years, there has been a new gold rush with several persons becoming smallscale miners to escape complete social marginalization. Coupled with this, is ...
